Abstract
The utility model relates to a take finish rolling screw -thread steel anchor backing plate of slip casting coupling, include anchor backing plate, location steel pipe, slip casting pipe tube head, end the thick liquid ring, its characterized in that: location steel pipe vertical welding just fixes a position steel pipe axis and anchor backing plate mesopore dead in line at the anchor backing plate back, slip casting pipe tube head vertical welding forms the tee bend structure on the steel pipe of location. Be connected position department installation plastics at anchor backing plate and location steel pipe and end the thick liquid ring. The utility model discloses the preparation of anchor slab, except that conventional anchor backing plate, the processing of the equal usable waste material of other parts forms. The utility model provides a when adopting the construction of conventional anchor backing plate, the biased height of slip casting pipe, slip casting pipe and bellows joint position be sealed to be handled loaded down with trivial details, slip casting pipe and bellows and connects a following position slip casting difficult problem such as not full, the easy operation that constructs simultaneously can accelerate construction speed, can solve a series of potential quality problems that conventional construction method was brought.
Description
Technical field
The utility model belongs to engineering field, relates to the fining twisted steel field used in engineering design and construction, particularly a kind of fining twisted steel anchor plate with Grouting Pipe joint.
Background technology
Bridge engineering many employings fining twisted steel as bridge vertical prestressing bar, and all adopts post-tensioned construction.And in structural concrete work progress, fining twisted steel need adopt bellows protection, treat that structural concrete has been built, after fining twisted steel stretch-draw, adopted at bellows internal pore position grouting agent to be filled with real again.At present, comparatively common way is: first at conventional anchor back welding spiral bar, then fining twisted steel, bellows, anchor plate, nut have been assembled successively, finally in 500 ~ 1000mm place, termination boring bottom bellows, Grouting Pipe is stretched in bellows, and adopts adhesive tape to be sealed by joint area.When adopting the method construction, Grouting Pipe and the bellows junction distance of positions are comparatively large from corrugated tube end length, join mouth and be difficult to pour into lower portion closely knit during slip casting; Grouting Pipe and bellows join position and adopt adhesive tape to be wound around, and constructing operation is very loaded down with trivial details; Bellows and fining twisted steel are without location measure, and easy and fining twisted steel is close to, and fining twisted steel surrounding slip casting thickness differs.
Summary of the invention
The purpose of this utility model in order to overcome above-mentioned prior art Problems existing and shortcoming, and provides a kind of fining twisted steel anchor plate with Grouting Pipe joint.The utility model, without the need to too much input, makes material and the waste material in work progress can be utilized to process.
The technical solution of the utility model is:
With a fining twisted steel anchor plate for Grouting Pipe joint, comprise anchor plate, positioning steel tube, Grouting Pipe tube head, grout stop, it is characterized in that: positioning steel tube is vertically welded in the anchor plate back side, and positioning steel tube axis and the dead in line of anchor plate mesopore; Grouting Pipe tube head is vertically welded on positioning steel tube, forms three-port structure.
The utility model also comprises grout stop, and grout stop is arranged on anchor plate and positioning steel tube connecting portion place, and when preventing concreting, cement paste enters the blocking Grouting Pipe mouth of pipe in bellows.
Described positioning steel tube external diameter is identical with the inside diameter of bel of required location, prevents bellows and fining twisted steel to be close to.
Only Grouting Pipe need be adopted to be connected with Grouting Pipe joint after all parts installations, grouting port is connected to structure outward.
When this anchor plate is arranged on bottom fining twisted steel, Grouting Pipe tube head can be used as slip casting import after connecting Grouting Pipe, can be used as venthole when being arranged on fining twisted steel top.
Described anchor plate is conventional anchor backing plate, and its back side is welded with spiral bar.
Described positioning steel tube length is 100mm, and external diameter is identical with located inside diameter of bel, and bellows positioning steel tube and anchor plate adopt and be welded to connect, positioning steel tube axis and the dead in line of anchor plate mesopore.
Described Grouting Pipe tube head length is 50mm, the Grouting Pipe diameter compatible cover of its diameter and employing, and its internal diameter is not less than 20mm; Grouting Pipe tube head and positioning steel tube vertical welding, joint area is in the middle part of positioning steel tube, and the positioning steel tube tube wall of joint area answers perforate, and aperture is identical with Grouting Pipe tube head internal diameter and be not less than 20mm, should ensure in tee piece unobstructed after having welded.
Described grout stop is plastic material, and its internal diameter is slightly less than positioning steel tube external diameter, can ensure bellows and anchor slab joint area not spillage.
The making of the utility model anchor slab, except conventional anchor backing plate, other parts all can utilize waste material to process.When the utility model solves and adopts the construction of conventional anchor backing plate, the biased height of Grouting Pipe pipe, Grouting Pipe and corrugated pipe connector position encapsulation process are loaded down with trivial details, Grouting Pipe and corrugated pipe connector be with difficult problems such as lower portion slip casting are not full; Constructing operation is simple simultaneously, can accelerate speed of application, can solve a series of potential quality problems that conventional construction method is brought.

Detailed description of the invention
The utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model comprises anchor plate 1, positioning steel tube 2, Grouting Pipe tube head 3, grout stop 4, before installing, positioning steel tube 2 is vertically welded in anchor plate 1 back side, and positioning steel tube 2 axis and the dead in line of anchor plate 1 mesopore; The long 100mm of positioning steel tube 2, external diameter is identical with the inside diameter of bel of required location; Grouting Pipe tube head 3 and positioning steel tube 2 vertical welding, form three-port structure; Grouting Pipe tube head length is 50mm, the Grouting Pipe diameter compatible cover of Grouting Pipe tube head diameter and employing, and internal diameter is not less than 20mm; For when preventing concreting, cement paste enters bellows, at anchor plate 1 and positioning steel tube 2 connecting portion place, the grout stop 4 of plastics is installed.
As shown in Figure 4, anchor plate 1 to be arranged on after completing on fining twisted steel 5 and at fining twisted steel end mounting nuts 6 by anchor slab; Before bellows is installed, axially offers a wide 20 ~ 25mm notch of long 60mm at corrugated tube end along it, Grouting Pipe tube head 3 is stuck in notch, ensure that bellows end women's head-ornaments and anchor plate 1 are close to, grout stop 4 is enclosed within outside bellows simultaneously.Finally the spiral bar of code requirement and anchor slab reinforcing rib are welded on anchor plate 1 back side.Can the fining twisted steel of making be arranged in structure after completing above work, connect a slip casting flexible pipe at Grouting Pipe tube head position simultaneously, slip casting flexible pipe is connected to outside structure, and guarantees that pipeline is unimpeded; Bottom fining twisted steel, slip casting flexible pipe is as slip casting inducer, and slip casting flexible pipe in top is as slip casting venthole.
